HAY-BALING DEVICE.

Specification of Letters Patent.

Patented May 14, 1907.

Application nei ipiiiizr, i906. sein No. 313,366.

To a/ZZ whom t may concern.'

Be it known that I, MARVIN MEAD, residing at Pueblo, in the county ofPueblo and State of Colorado, have invented certain new and usefulImprovements in I-Iay-Baling Devices; and I do declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and to theletters and figures of reference marked thereon, which form a part ofthis specification.

My invention relates to an improvement in hay balers, or especially tothe form and location of the levers and manner of transmitting the powerfrom the lever horse power to the plunger of the baler.

One object in this device is to provide a baler that the bale chambercan remain on the transporting wheels while in operation far enoughabove the ground or floor for the push and pull bar or cable, and thebridge plank to be underneath the said bale chamber and axles and nearlyhat on the ground in line with a low down horsepower, making said powerconnection without any obstruction for the team to pass over.

Another object in this device is to apply the power to the centerpressure of the plunwithout any pitrnan, cam, jointed lever 0r any othercumbersome and heavy fixtures Aor connections, applying the powerdirect, so there can be no trouble from buckling or springing up of thebridgeplank or pushbar.

A still further object is to provide a baler that is strong and durablewith less weight, shorter, less number of parts, easy to transport andoperate, and that can be set with one end or either side of the feedhopper to the stack.

In the drawings forming a part of this specification, Figure 1 is aperspective view of the parts of a baling press constructed inaccordance with my invention. Fig. 2 is a side view showing the positionofl vertical side levers, as applied to an ordinary bale chamber; Fig. 3is a front elevation of the plunger shown by dotted lines in Figs. 1 &2. Fig. 4 is a view of a depending bracket 'or brace to support thebridge or push plank, between the power and bale chamber.

B Fig. 2, is a side plates of the bale chamb, dotted lines showing thesliding plunger 2 2 @c 2, Fig. 3, are portions of 2A, in the form oflugs, extending ont on either side.

The side pl atesB are divided or slotted at 5, Fig. 1, and made strongby bars G6, form ing ways and guides for the lugs 2, of the plunger 2A,to travel in.

The lugs 2-2, are'the central moving fulcrums for the vertical levers1--1, and hold them in place, as they force the plunger forward to pressthe bale.

7 is a link pivoted at S, to post 9, and brace 10, and also to the upperend of lever 1 at 12, forming a rigid horizontal fulcrum and permittinga vertical movement, suflicient to carry the central pivot of the lever,Kin the parallel slot of the side plate. The pull rod or cable 14,.isdivided under the press and held so by the spreader 15, the prongs 3,are pivoted to the levers` 1 -il at I4l, :nid the single end to the lowdown pon-'ein rllie re turn spring 13, is adjustable and can be hookedto the lever at any place .to give the plunger more or less help toreturn` In Fig. L1,-16 is a double bracket fastened and braced to thesills of the bale chamber, depending down to support the bridge or pushplank 17, and low enough for the pull rod 14 or a cable to pass or slideover or above the plank. There is an opening in the bracket 16, to allowthe rod 14 to pass through over the bridge 17. The bridge plank 17 ismovable, and when the baler is in operation the plank is placed betweenthe horsepower and the press, to counteract the pull of the rod, or as abrace to prevent the power and ress from being drawn toward each other.

It will thus be seen that I provide a baler that is light and strong,that can remain on the trucks while in operation,with light movable andflexible connections, under the press andlflat to the ground. for theteam to pass over.

Having thus fully described iny invention, what I claim as new anddesir-elio secure by vLetters .Patent is 1. In. combination, a balechamber having slots in its sides, guide plates arranged ad jacent theslots, a plunger within the chalnber, trunnions on the 'plunger'extending through the slots between the guides, levers mounted on thetrunnions el' the plunger, links pivoted. to the upper ends el' tlielevers, said links being carried by the clnnnber,

the levers.

and pull rods connected to the opposite ends of TOO ITO
